Extreme batch at Dwarka centre compromises of the top students of Dwarka centre
whereas the regular batch at VMC Pitampura consists of normal students at Pitampura centre.
From my own experience I would suggest take VMC Pitampura regular batch.

I had faced the same situation three years back and I regret taking VMC Dwarka.
The faculty at VMC Pitampura will be way better than VMC Dwarka and also VMC Pitampura is considered as the main branch.

Also in the two years that you would be enrolled if you chose VMC Dwarka, chances are very high that in any one of those years you will get either one of these two sirs (Rajeev Sir And Praveen Sir) as your physics teacher and that will totally mess up with your physics. The former one doesn't teach mains level as in the level of questions and concepts that he teaches are below the Mains level and the latter one doesn't even teach basics, he just starts with Advance level and being fresh out of 10th or even 11th you first need to strengthen your basics then move ahead.
